After updating from an older version to v0.33.4, there doesn't seem to be a way to reverse the y-axis.
Flipping the y-axis is useful when using a metric like average ranking position so 1 is at the top. This feature is available in other tools like Excel or Google Data Studio.
We were previously using the hacky trick of unchecking "Auto y-axis range" and setting the Min above the Max but that doesn't seem to work now...
